My invention relates to refrigerating systems, and particularly to systems for'coohng air for refrigerating rooms such as are required for meat storage.

In meat storage rooms a number of different types suggested. One type of system which'is 1n quite general use is linin the walls of the storage room with pipes through whlch cold brine is circulated. ir passing in the vicinity ofthe cold brine pipes is cooled and tends to move down to the lower part of the room, being replaced by warmer air which circulates upwardly. Another system is to provide conduits with a brine'spray so arranged in the conduit'that air is drawn from the top of the room and is blown inwardly from the walls of the room against the 'hangin meat. Thelatter system tends to cause consi erable condensation on the ceiling of the room, and the fwater dripping down has a deleterious effect on the meat. Further, directing blasts oficool air directly against the meat tends to d it out.

t is the object of my invention to provide a refrigerating system in which condensation on the walls and ceiling of the storage room is avoided. It is also an object to irect currents of cooled air from the side walls of the room close to the ceiling outwardly, so that the air will move in currents down and around the meat and refrigerate it evenly without causing a tendency to dry out.

The above objects and others to which ref- 7 erence will be made in the ensuing disclosure I.-accm lish by that certain arrangement and comhination of parts of which I have shown a preferred modification, with arrows indicatingthe direction of cooling air currents which I desire to maintain.

In the drawings z- Figure 1 is a perspective view with parts cut away to show the internal structure of a preferred type of air cooler.

Figure 2 is a sectional view of a refrigerating room showing a preferred arrangement of air coolers and also with arrows indicating theodirection of air currents which I maintain in accordance with my system.

I haveiprovided a casing which is subof refrigerating systems have been divided by walls 1 into three compartments. The first compartment indicated, in the drawings at2 has an air intake opening 3 at the bottom. The wall 1 at the top is cut away.

so that aspace 4; rmits therising air to be as drawn downwa y in a central chamber 5 b means of; a brine spray pipe 6 which sip ons the air downwardly in the chamber 5 and causes it to be forced u wardly in the chamber 7, from which it isb lownnut at the top through an opening 8. 'I have indicated .a sect1on of pipe 9 within which the spra pipe 6, rotrudes in order to increase the s1- 6 phone ect of the spray. The brine flows out from the central chamber through a dis-- charge pi 6 from which it is returned to the re rigerating' system and circulated throughitl I Y A desired number of these air cooling units are placed along the walls of the refrigeratmg room, which I have indicated at 10. The 'meat to be refrigerated, which I have indicated by thecarcasses 11, is suspended by means of hooks 12 from tracks 13 which are conveniently arranged so that the carcasses can be moved to and from the refrigeratin room. Currents of air being drawn u war 1y through the openings 3 are sucke down throu h the middle compartments and then force upwardly, discharging out of the so opemngs 8. From the openings 8 the currents pass outwardly toward the top of the meat. 0 Due to being cooler than the surrounding air the currents circulate gently in and aroundthe han 'n carcasses, and are gently wafted towar s t e floor, from which they are again recirculated up'through the air coolin devices. 7 I find t at with the system of refrigeratm or coolingwhich I have described, the 00 d air currents at the to of theroom prevent any condensation w ich would result in water drippin down on to the meat. Further, due to the arge s ace occupied by the gently downwardly 'wa ing currents at the center of the room in and around themeat, there is no tendency for the meat to dry out and become discolored. While I have shown one type of air cooler which I have found to be entirely practical and economical to construct and maintain, other devices for directin the cooling air currents in accordance wit my system may be employed.

5 Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a refrigerating system for a meat storage room having means for suspending 1o meat medially of the room, air cooling means havin an intake at its bottom, located'at the side 0 the room, said cooling means having air current inducing means for projecting cooling air currents outwardly from the tops of said inducing means toward the top portions of the sus ended meat so that it will waft in large vo ume down around the meat and be drawn in at the bottom of said inducing means.

2. A refrigerating device for meat storage rooms comprising a casing subdivided into vertically arranged compartments, one compartment having intake means at its bottom, a pasage connecting said compartment at its top to an adjacent middle compartment having an intake at its top, a passage connecting the bottom of said middle compartment with the bottom of an upwardly extending discharge compartment having an opening at the top thereof, and spray means for cooling and inducing a draft of air currents through said compartments, said spray means located in said middle compartment.
